Real Estate Pay-Per-Call Advertising is new, though far from reaching the popularity of "pay per click." But for service sector businesses like real estate brokers and real estate agents that rely more on the telephone than the Web for business, buying calls instead of clicks makes more business sense.

A real estate broker is a term in the United States and Canada that describes a party who acts as an intermediary between sellers and buyers of real estate (or real property as it is known elsewhere) and attempts to find sellers who wish to sell and buyers who wish to buy. In the United States, the relationship was originally established by reference to the English common law of agency with the broker having a fiduciary relationship with his clients.

The Real Estate Appraisal, property valuation or land valuation is the practice of developing an opinion of the value of real property, usually its Market Value. The need for appraisals arises from the heterogeneous nature of property as an investment class: no two properties are identical, and all properties differ from each other in their location - which is one of the most important determinants of their value. So there cannot exist a centralised Walrasian auction setting for the trading of property assets, as there exists for trade in corporate stock. The absence of a market-based pricing mechanism determines the need for an expert appraisal/valuation of real estate/property.
